Hi. I am trying to modify kmeans function. It seems that is failing something obvious with the workspace. I am a newbie and here is my code: myk = function (x, centers, iter.max = 10, nstart = 1, algorithm = c("Hartigan-Wong", + "Lloyd", "Forgy", "MacQueen")) + { + do_one <- function(nmeth) { + Z <- switch(nmeth, { + Z

I am running a k-means clustering code in R : mydata_kmeans5 <- kmeans(mydata, centers=5).. But the problem is that the data is having some "NA" in it. So R is showing me a message :Error in switch(nmeth, { : NA/NaN/Inf in foreign function call (arg 1) In addition: Warning messages: 1: In switch(nmeth, { : NAs introduced by coercion 2: In switch(nmeth, { : NAs introduced by

Hi, according to http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/amr/amr.c?only_with_tag=RELENG_6 it seems MegaMGR for linux now can work. Any experience? -- Cris, member of G.U.F.I Italian FreeBSD User Group http://www.gufi.org/

Hi, Thank you for your work on this card! I have quite a few boxes that run various 3wares cards with diverse firmware revs. Are there any caveats with respect to models and firmware versions in terms of how they might interact ? ---Mike At 01:25 PM 10/08/2003 -0700, Paul Saab wrote: >ps 2003/08/10 13:25:46 PDT > > FreeBSD src repository > >

Hi: How do I find average across three columns such as weight1, weight2, weight3 (20 people, each person has three different measures)? They have NA's also. Thanks Tom, Univ of Pittsburgh, ttrut at yahoo.com

Let's say you have a dataframe of car trade-ins. For example, each row contains oldcar newcar qty and a typical entry could be lexus bmw 1 I put the qty column to allow for fleet purchases, where one purchase may convert multiple cars at once. I'd like to show what's going on. I could do a histogram of newcar to show the frequency each type of car is bought. If there

even for people who didn't like the outcome of the US elections this year, it must have been a joy to see all the nice (and not so nice) graphs that were shown. As an exercise, I recreated the map shown on the NY-Times website [ http://www.nytimes.com/packages/khtml/2004/11/03/politics/ 20041103_px_ELECT_GRAPHIC.html ] If you're interested,

I created patch for DragonFly/FreeBSD-4 for prebinding, based on mdodd@'s patch for FreeBSD-5. The main difference (apart from the target platform) is that the linker needn't be patched. Rtld now uses a hash function to get an unique ID for every ELF object. This has been tested under DragonFly, but should run on FreeBSD-4 too. Feedback appreciated :) cheers simon -- /"\

Hi, I have a question about exporting interactive 3D plots. I use the following code to plot a contour of a trivariate normal distribution: library(mvtnorm) library(rgl) library(misc3d) n=25 x=seq(-3,3,length=n) X=cbind(rep(x,each=n**2),rep(rep(x,each=n),n),rep(x,n**2)) p=array(dmvnorm(X,sigma=diag(3)*0.5+0.5),c(n,n,n)) contour3d(p,x,x,x,level=mean(p)) lim=c(-3,3)

Hi, [some background] I have a dataset which describes a number of subjects doing a "scientific discovery". That is, they have to discover the rules underlying a particular domain. To do so, they have to set the levels of 5 variables which leads to a certain outcome. To identify what kind of "experiments" the subjects did, I want to combine these levels into one variable
